4X4 SERVICES

The technicians at John's Service Center have years of experience working on standard 4-wheel drive (4x4) vehicles as well as all-wheel drive (AWD) vehicles. AWD is a full-time 4-wheel-drive system (all four wheels receive torque from the engine simultaneously) that employs a center differential that allows each tire to rotate at different speeds.

We understand the special needs of these vehicles. These are some of the services we offer.

AlignmentWheel alignment (or simply alignment) is standard car maintenance that involves adjusting the angles of the wheels so that they are set to the manufacturer's specifications. The main purpose is to let the suspension and the steering systems operate at their desired angles - this reduces tire wear. Alignment is a complicated process and not all mechanics get it right. To have experts handle your car's alignment, visit John's Service Center.

DifferentialsThe differential transfers the engine power to the wheels. One important function of the differential is to pass on power to the wheels while allowing them to rotate at different speeds - thus the name differential. When turning, the outer wheels travel a larger distance than the inner wheels do (also the front wheels travel a longer distance than the rear wheels). This means that all four wheels travel at different speeds during a turn and this is where the differential comes in to help. To make sure your vehicle's differentials are working properly, have them checked regularly. Contact John's Service Center today for differentials examination and servicing.

DrivelineA driveline is a part of your motor vehicle that connects the engine and the transmission to the wheel axles. The driveline consists of the parts of the powertrain less the engine and transmission. Failure of the driveline means that the car would not move since energy cannot be transmitted from the engine to the wheel axles. Therefore, make sure that your car's driveline is regularly inspected and serviced. And, at John's Service Center, you can have the driveline serviced by experts.

Hubs, Seals, Studs, & NutsA wheel hub motor, also referred to as a wheel motor, is an electric motor incorporated into the wheel hub and drives it directly. You can have a safer and smoother ride today by replacing your warped and worn out wheel hubs. Let John's Service Center replace your worn out hubs today.

Properly working seals provide oil and grease sealing - offering enhanced performance in a wide range of temperatures and environments. Worn out or warped seals allow external contaminants to enter the bearing unit or let lubricant escape from the unit. This ultimately leads to premature failure of the bearing unit. To keep out contamination and retain lubricant in the bearings, have the seals replaced with new ones. To have the seals replaced by experts, contact or visit John's Service Center today.

Studs are the threaded fasteners that hold on the wheels of your truck. The wheel studs are permanently mounted on the wheel hub through the brake disk or brake drum. To secure the wheel, nuts (lug nuts) are fastened over the stud. Stripped wheel studs can be quite dangerous. Damaged wheel studs should be replaced with new ones immediately. To have your truck's wheel studs replaced with high quality ones, call 215-295-3550 or visit John's Service Center today.

A wheel nut or lug nut is a fastener for securing a wheel on the hub. A set of lug nuts are used to secure a wheel to the threaded wheel studs (which are fixed to a wheel hub). Worn out nuts means one thing - the wheel is not fixed securely on the vehicle which puts the vehicle at the risk of rolling over. To have your truck's wheels securely fastened to the hub, contact or visit John's Service Center in Morrisville, PA 19067 today.

Transfer CasesA transfer case is a part of a four wheel drive system found in four wheel drive and all wheel drive vehicles. The transfer case receives power from the transmission and sends it to both the front and rear axles. This can be done with a set of gears, but the majority of transfer cases manufactured today are chain driven. The transfer case is connected to the transmission and also to the front and rear axles by means of drive shafts. Trust the automotive experts at John's Service Center for all your transmission repairs.

TransmissionsTransmission repair is not something to take lightly. The transmission is connected to key parts of your vehicle and needs to be working properly for your safety. Transmission services include replacing filters and draining fluids to prevent transmission damage. Typical transmission issues that may lead to repair may include shifting issues, slipping, stalling, fluid leaking, and the service light turning on. If you are concerned that you may need transmission repair, don't hesitate to schedule an appointment at John's Service Center today.

Wheel BearingsWheel bearings are found inside of wheels, allowing the wheels to spin freely, and are connected to the brake system. They can become worn over time, causing a vibrating suspension and noisy rubbing as the car is driven. If they break completely, the vehicle will become very difficult to control and unsafe to drive. Replacement interval for wheel bearings varies greatly, but they should be checked for leaks and wear periodically. John's Service Center can make sure that your bearings are in good shape and let you know if they need replacement.

Have Questions?

Vehicle Tips

According to recent studies, 5 percent of all motor vehicle fatalities are clearly caused by automobile maintenance neglect.

Vehicle Tips

The cooling system should be completely flushed and refilled about every 24 months. The level, condition, and concentration of coolant should be checked. (A 50/50 mix of anti-freeze and water is usually recommended.)

Vehicle Tips

Never remove the radiator cap until the engine has thoroughly cooled. The tightness and condition of drive belts, clamps and hoses should be checked by a pro.

Vehicle Tips

Change your oil and oil filter as specified in your manual, or more often (every 3,000 miles) if you make frequent short jaunts, extended trips with lots of luggage or tow a trailer.

Vehicle Tips

Replace other filters (air, fuel, PCV, etc.) as recommended, or more often in dusty conditions. Get engine drivability problems (hard stops, rough idling, stalling, diminished power, etc.) corrected at a good shop.

Vehicle Tips

A dirty windshield causes eye fatigue and can pose a safety hazard. Replace worn blades and get plenty of windshield washer solvent.

Vehicle Tips

Have your tires rotated about every 5,000 miles. Check tire pressures once a month; let the tires cool down first. Don't forget your spare and be sure your jack is in good condition.

Vehicle Tips

Vehicle Tips

Inspect the engine's belts regularly. Look for cracks or missing sections or segments. Worn belts will affect the engine performance.

Vehicle Tips

Have the fuel filter changed every 10,000 miles to prevent rust, dirt and other impurities from entering the fuel system.

Vehicle Tips

Change the transmission fluid and filter every 15,000 to 18,000 miles. This will protect the precision-crafted components of the transmission/transaxle.

Vehicle Tips

Inspect the suspension system regularly. This will extend the life of the vehicle's tires.
